EGG-TESTER.

SPECIFICATION forming part of Letters Patent No. 717,343, dated December30, 1902.

Application led May 26,1902. SerialNo. 108,947. (No model.)

To LZZ whom. it may concern: I

Be it known that I, JOHN CARLEN, a citizen of the United States, and aresident of Havana, in the county of Sargent and State of North Dakota,have invented a new and Improved Egg-Tester, of which the following is afull, clear, and exact description.

This invention relates to improvements in machines for testing eggs, theobject being to lo provide a device of this character of simpleconstruction and by means of which eggs may be rapidly and accuratelytested.

'I will describe an egg-tester embodying my invention and then point outthe novel fear5 tures in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ot'this specification, in which similar characters of reference indicatecorresponding parts in-all the figures.

zo Figure 1 is a sectional elevation of an eggtester embodying myinvention. Fig. 2 is a plan view thereof with the top of the darkchamber removed to more clearly show other parts, and Fig. 3 is asection on the line 0c a: of Fig. 2.

Referring to the drawings, 1 designates a tray into which the packedeggs are designed to be placed, and arrangedunderneath the trayisahopper 2 for receiving the bran, oats,

3o or the like in which the eggs are packed, the same passing throughopenings 3, formed in the bottom of the tray. It is to be understood,however, that instead of forming the openings 3 directly through thewooden bottom of the tray a bottom of wire-netting or the like may beplaced over the hopper. The

lower end of the hopper is provided with a sliding closure 4, whichmaybe opened to discharge the packing material.

Arranged in one side of the tray is a casing 5, in which a lamp 6 isdesigned to be placed.

This casing is provided with openings at opposite sides for the purposeboth of ventilation and of permitting access to regulate the i lamp.

l that it may swing outward to permit the eggs to pass. At the lowerportion this swinging wall 9 has an opening 10, through whichlight maypass to the egg directly in front of it. The side walls of the darkchamber 7 at the 55 bott-om are provided with openings, and over theseopenings are secured curtains 11, of flexible material-such, forinstance, as rubber-and each curtain is provided with an opening 12,which will be substantially the 6o size of a small egg; but to permitlarge eggs to pass through the same readily the flexible material 1l isslitted from the walls of the opening 12 outward, as clearly indicatedin the drawings.

Mounted to rotate in the tray is an egg-carrier consisting of a disk 13,having around its edge a series ofopenings 14., in which eggs aredesigned to be placed, and from each opening 14 there is an outwardopening 15, which per- 7o mits the light to strike upon all portions ofthe egg in line with the opening 10. This carrier 13 projects underneaththe dark4 chamber 7 and somewhat into the casing 5, as clearly shown, inFigs. 2 and 3. The carrier 13 is 75 mounted on a spindle 16, which has abearing in a cross-bar 17, arranged in the tray.

At one end of the machine I provide a folding frame17, upon which theegg-cases may be placed to receive the tested eggs. The up- 8o perportions of this frame 17 are pivoted to the legs supporting the tray.

In operation the eggs to be tested are placed in the openings lll andthe carrier 13 slowly rotated to bring the eggs successively in front ofthe opening 10, so that the same may be observed through the sight-tube8. The openings 14 are so spaced that the openings 12 of the curtains 11will be closed by eggs while an egg is in line with the opening 10, thus9o excluding all light. 5

Having thus described my invention, I claim as new and desire to secureby Letters Patenti l. An egg-tester comprising a tray, a casing thereinadapted to receive a lamp, a dark chamber at one side of the casing, asighttube leading into said dark chamber, a swinging wall between thedark chamber and casing, the said swinging wall having an openloo asspecified.

2. An egg-tester comprising a tray, a easing therein adapted to receivea lamp, a dark chamber inward of the casing, a swinging wall between thedark chamber and casing, the said swinging wall having an opening at itslower portion, a sight-tube leading into the dark chamber and in linewith said opening, fiexible curtains at the sides of the dark chamberand having openings for the passage of eggs, and a carrier consisting ofa disk having openings to receive eggs, said carrier being mounted torotate, substantially as specified.

3. An egg-tester Comprising a tray, a oasing arranged in the tray andadapted to receive a lamp, a dark chamber at one side of the casing, aswinging wall between the dark chamber and casing, the said swingingwall having an opening at the bottom, a sightt-ube leading into the darkchamber, curtains arranged over openings in the side walls of the darkchamber, the said curtains having openings for the passage of eggs andthe material of the curtains being slitted outward from said openings,and a rotary carrier for moving eggs through the dark chamber,substantially as specified.

4. An egg-tester comprising a tray, a oasing arranged in the tray andadapted to reeeive a lamp, a dark chamber arranged at one side of thecasing, a swinging wall between the dark chamber and casing, the saidswinging wall having an opening at the bottom, a sight-tube leading intothe dark chamber in line with said opening, curtains over openings inthe side walls of the dark chamber, the said curtains being providedwith openings, and a carrier consisting of a rotary disk having openingsto receive eggs and openings outward from the first-named openings,substantially as specified.

5. An egg-tester comprising a tray, a dark chamber arranged in the tray,a sight-tube leading into the dark chamber, a receptacle for alight-giving device, a swinging Wall between the dark chamber and saidreceptacle, the said wall being provided with an opening at the bottom,the side walls of the dark chamber being provided with openings,curtains of exible material over said openings and provided withopenings, a carrier consisting of a disk mounted to rotate and having aportion extended into said dark chamber and also into the receptacle,and a hopper arranged underneath the tray, the said tray having openingsin its bottom wall over said hopper, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN CARLEN.
